Cutting torch pendulum angle conversion device

Abstract

The invention discloses a cutting torch pendulum angle conversion device. The cutting torch pendulum angle conversion device comprises a foundation frame, a driving wheel, a driven wheel, a first connecting rod, a second connecting rod, a clamping mechanism and a synchronous mechanism. The foundation frame is provided with a vertical foundation plate. A servo motor, a second shaft lever assembly and a fourth shaft lever assembly are sequentially installed on the foundation plate from top to bottom. An output shaft of the servo motor is connected with a small gear. The driving wheel is of a gear structure, installed on the second shaft lever assembly and engaged with the small gear. A first shaft lever assembly is arranged on the driving wheel. The driven wheel is installed on the fourth shaft lever assembly and provided with a third shaft lever assembly. The first connecting rod is connected with the first shaft lever assembly and the third shaft lever assembly, and one end of the first connecting rod extends out of the lower portion edge of the driven wheel. The two ends of the second connecting rod are connected with the driving wheel and the driven wheel respectively, and the second connecting rod is parallel to the first connecting rod. The clamping mechanism is transversely installed at the tail end of the first connecting rod. The synchronous mechanism is arranged between the third shaft lever assembly and the clamping mechanism.

Description

technical field [0001] The invention relates to auxiliary equipment for cutting torches, in particular to a cutting torch swing angle conversion device. Background technique [0002] In the welding process, in order to ensure the welding quality, it is necessary to use a plasma or flame cutting torch to cut a bevel on the part. During the groove cutting process, the cutting torch needs to be tilted according to the design angle of the groove on the part, so that the welding groove that meets the design requirements can be cut on the part. [0003] During the cutting operation, the torch is clamped on the auxiliary clamping equipment to realize the corresponding tilting operation. At present, the common auxiliary clamping equipment is mainly composed of a rotating device and a worm reducer. The output end of the worm is used to install the cutting torch, and the input end of the worm is used to install the servo motor. The entire worm reducer (together with the cutting torch...

Problems solved by technology

However, because the overall weight of the worm gear reducer is relatively heavy, it causes a high rotational load on the rotating device, and the high rotational load easily affects the stability and flexibility of the motor of the rotating device, and the worm gear transmission efficiency is low, and the clearance Large, which will lead to a large error in the inclination angle of the cutting torch, so the angle error of the groove cut on the part is relatively large, the repeatability is poor, and it is not stable and reliable enough.
